Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 810F10R is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 10 Ohms
• Tolerance: ±1%
• Composition: Wirewound
• Temperature Coefficient: ±20ppm/°C
• Housing Type: Aluminum
• Mounting Feature: Flanges
• Lead Style: Solder Lugs
• Package Type: Axial, Box

Allowable Variation Parameters:

• Power Rating: Equal to or greater than 10W
• Operating Temperature Range: Must accommodate the application's thermal requirements
• Physical dimensions: Minor variations acceptable within standard chassis mount resistor envelope
• RoHS and compliance status: May differ based on application requirements

The identified substitutes meet these criteria while offering either improved product status (active vs. obsolete) or enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

810F10RE (ARCOL) is the primary equivalent for direct replacement. This part maintains identical electrical specifications (10 Ohms, ±1%, 10W, ±20ppm/°C) and mechanical configuration while offering active product status and RoHS compliance. The part is available in bulk packaging with 1295 units in stock. Physical dimensions show minor variation (0.783" L x 0.827" W vs. 0.750" L x 0.812" W), which remains within acceptable chassis mount resistor envelope tolerances.

RH01010R00FC02 (Vishay Dale) provides an alternative with increased power rating (12.5W vs. 10W), offering thermal margin for applications with variable load conditions. This part maintains the same resistance, tolerance, and temperature coefficient specifications. The operating temperature range is reduced to -55°C ~ 250°C compared to the original 275°C maximum. This part is suitable for applications where the lower temperature ceiling does not present a constraint. Moisture-resistant features are included. RoHS non-compliance status matches the original part.

Selection between these substitutes depends on compliance requirements and thermal design margins specific to the application.

Frequently Asked Questions (FAQ)

Q: Can 810F10RE be used as a direct replacement for 810F10R? A: Yes. The 810F10RE maintains identical electrical parameters (10 Ohms ±1%, 10W, ±20ppm/°C) and mechanical mounting configuration. Minor physical dimension variations fall within standard chassis mount resistor tolerances and do not affect mounting or thermal performance in typical applications.

Q: What is the advantage of RH01010R00FC02 over 810F10RE? A: The RH01010R00FC02 provides 12.5W power rating versus 10W, offering additional thermal headroom. Both parts maintain identical resistance, tolerance, and temperature coefficient specifications. Selection depends on whether the application requires this additional power margin and whether the -55°C ~ 250°C operating range is acceptable versus the original 275°C maximum.

Q: Are there compliance differences between the substitutes? A: Yes. The 810F10RE is RoHS compliant, while both the original 810F10R and RH01010R00FC02 are RoHS non-compliant. Applications subject to RoHS requirements should specify 810F10RE. The RH01010R00FC02 carries REACH Affected status, while 810F10R carries REACH Unaffected status.

Q: Do physical dimension differences affect mounting? A: The substitutes show minor dimensional variations within the chassis mount resistor standard envelope. The 810F10RE measures 0.783" L x 0.827" W (vs. 0.750" L x 0.812" W original), and RH01010R00FC02 measures 0.750" L x 0.800" W. These variations are typical for this component category and do not affect standard flanged mounting applications.

Q: Which substitute should be selected for new designs? A: For new designs, 810F10RE is recommended due to active product status, RoHS compliance, and identical electrical specifications. For applications requiring additional thermal margin, RH01010R00FC02 provides 12.5W rating with the same precision specifications.
